Project ARTEMIS: A Mechanistic Clinical Trial of Neuroimmune Pathways.
Wake Forest University Health Sciences
Summary
The purpose of this research is to understand how chronic stress affects the way our brain and immune systems function, and in turn how this affects the way people feel, think, and behave. By learning more about how these processes work, the hope is to be able to develop better treatments to help with problems like depression and substance use. This study is intended for individuals that are HIV positive, currently taking prescription antiretroviral medications, and use stimulants. Through this intervention, the aim is to determine if this positive affect intervention can lead to reductions in stimulant use and depressed mood.
Description
Participants who meet initial eligibility criteria will complete a baseline assessment that includes psychosocial and behavioral measures, biospecimen collection, and an MRI brain scan. Participants will then be randomized to either: 1) ARTEMIS; or 2) a waitlist control (WLC) condition. ARTEMIS participants will receive 5 sessions delivered individually over Zoom across 3 months. All participants (including WLC) will receive contingency management (CM) for antiretroviral therapy (ART) adherence to support sustained viral suppression over the active phase of the trial. During the intent-to-trea…

Interventions
- BehavioralARTEMIS
The ARTEMIS intervention includes 5 sessions delivered individually over Zoom across 3 months. The intervention teaches 9 positive affect skills: noting and capitalizing on positive events, gratitude journaling, formal and informal mindfulness, positive reappraisal and problem solving coping skills training, focusing on personal strengths, setting achievable goals, and small acts of kindness. Each session consists of a didactic portion with in vivo skills practice, and participants are asked to complete daily home practice of the skills between sessions.
- BehavioralContingency management for Antiretroviral (ARV) adherence
All participants will received the contingency management (CM) intervention to support ARV adherence. They will use the Spotlight by Scene Health platform, a HIPAA-compliant mHealth application for directly observed therapy, to upload videos of ART adherence. The app records and uploads time-stamped videos of medication doses, which staff verify asynchronously. Participants will be paid for each verified dose and receive a weekly bonus if they complete 6 doses.
